What's this test for?

This test is ideal if you're recovering from a strep infection and your provider wants to confirm it was the cause of a related condition like a skin infection, kidney inflammation, or joint pain. It's also useful if you've had recent unexplained symptoms following a sore throat or skin rash and want to check whether strep bacteria were involved. The test looks for antibodies your body made in response to a substance released by group A strep bacteria.

What's included in this test?

This test measures a single antibody level in your blood that reflects your immune system's response to a recent group A streptococcal infection. It matters because strep infections can sometimes trigger complications elsewhere in the body, like the kidneys or joints, even after the original infection has cleared, so confirming past exposure helps explain those symptoms.

What happens after I get my results?

Your results will show up in your account with the normal range clearly explained so you can see exactly where your value falls. If your antibody level is elevated, a common next step is retesting in a few weeks to see if the level is falling, which typically means the infection is resolving. You can download a standard lab report from your account at any time, and the trends feature lets you track your antibody levels over multiple tests to watch your recovery progress.

How can I naturally support my immune recovery?

Getting enough sleep, staying hydrated, and eating a diet rich in fruits, vegetables, and lean protein all help your immune system clear an infection and recover fully. Light physical activity, once you're feeling better, can also support circulation and healing. Avoid smoking and limit alcohol, since both can slow down immune recovery. If you notice new or worsening symptoms like joint swelling or dark urine, seek medical care right away.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. Once processed, they'll be posted directly to your online account, and you'll be able to view and download the full report from there.

Who should consider this test?

This test is a good fit for anyone who recently had a sore throat, skin infection, or scarlet fever and is now dealing with unexplained joint pain, swelling, dark urine, or fatigue. It's also useful for people whose earlier strep test came back negative but symptoms suggest a past infection, since antibody levels rise even after the bacteria are gone. Parents monitoring a child's recovery after strep throat may also find this test helpful.

What symptoms indicate I may need this test?

Consider this test if you're experiencing joint pain or swelling, unusual fatigue, dark or foamy urine, swelling in your face or legs, or a skin rash that developed weeks after a sore throat or skin infection. These can be signs of a delayed immune reaction to strep bacteria. A recent history of strep throat or impetigo makes these symptoms more worth investigating.

What does a high DNase-B antibody level mean?

A high level usually means your body recently fought off a group A strep infection, even if you didn't realize you had one. It can help explain symptoms like joint pain or kidney irritation that started after the initial infection seemed to go away. The level often stays elevated for several weeks to months before gradually dropping as your body clears the response.

What causes a high DNase-B antibody result?

The most common cause is a recent strep throat or skin infection, such as impetigo, that triggered your immune system to produce these antibodies. Some people naturally have slightly elevated levels for longer periods, especially children, who are more frequently exposed to strep bacteria. Repeated or recent strep exposures can also keep levels elevated.

How often should I retest?

If your first result is elevated, retesting in 2 to 4 weeks is a common approach to see if the level is trending down, which suggests your body is clearing the infection response. If levels stay high or keep rising, that's worth noting and following up on. Otherwise, this isn't a test most people need to repeat routinely.
